WATER GATE-VALVE.

Specification of Letters Patent.

Patented Oct. 9, 1906.

Application filed August 9, 1905. Serial No. 273,385.

devices for controlling the flow of water in pipes.

It consists in a combination of mechanism and in details of construction which will be more fully explained by reference to the accompanying drawings, in which Figure 1 is a sectional view of my device. Fig. 2 is a section on line w as of Fig. 1. Fig. 3 isa section on line y y of Fig. 1. Fig. 4 shows the counterbalance-weight removed and a spring substituted.

My present invention is designed to provide improvements in the construction and operation of gates and valves which it is desired shall move transversely across the path through which the water passes.

My present invention is especially designed to be used in places where it is desirable to operate the valve from below or from one side, so that it maybe operated in either a vertical, horizontal, or inclined position, and for this purpose I employ counterbalance weights or springs which serve to maintain the valve in a position opposite to the water-passage until the compressive force by which it is closed has been released and also to place the valve in the closing position before the closing pressure is brought upon it.

A is a casing of any suitable or desired shape adapted to contain the gate mechanism. This case has openings 2 and 3 at opposite sides. These openings are in line with the conducting-pipes through which the water flows. Within this casing is a shell 4, which is fitted to slide transversely to the path of the water. The shell has shoulders 5, which travel against guides 6, these guides being disposed within the casing parallel with one of the sides of the casing, so that the movements of the shell during the opening and closing are properly guided.

The face 7 of the casing, against which the valve closes, is inclined, as shown, and the movements of the casing from the widest end thereof toward the narrower end gradually brings the valve into position to be closed against the seat.

The valve or gate 8 is connected with the side of the shell, which is contiguous to the inclined face 7 of the casing. The central portion of the valve has a projecting bar 9, which travels in a slot in the inclined face of the shell and rests against a roller 10. This roller extends transversely through a slot in the shell and forms an antifrictional support against which the valve or gate moves when subjected to pressure. More than one roller may be used, if desired.

v 11 represents levers fulcrumed in the easing, as shown at 12. One end of each of the levers is pivotally connected with the gate. The other ends of the leversextend into open channels, within which weights or equivalent springs 13 are movable.

When the apparatus is in a vertical position, the operation of the valve may be very well effected by counterbalance-Weightsg but if the valve is to be employed in any other than a vertical position springs may besubstituted for the weights. The tendency of these weights is to drop toward the lower end of the shell and through the levers the gate or valve will be raised toward the upper and narrower part of theshell.

Within the casing is a stop 14 upon the inclined face 7 and located above the opening against which the valve closes on this side. When the shell is raised, the upper edge of the valve or gate contacts with this stop when the valve has arrived at a substantially central position or coincident with the opening, so that when pressure is applied the valve will always be closed fairly against the opening. The inclined face of-the casing and that of the shell thus allow the valve to be free from pressure against its face when the valve is moved toward the wider part of the casing, and when this movement is effected the weightsor springs retain thevalve in contact with the stop and cover the opening in the casing until the shell has been moved so far as to relieve the valve from transverse pressure. The remaining movement of the shell then withdraws the valve from its closing position and opens the passage for the water, whichpassesacross the endof theshell when the gate is fully opened.

WVhen the valve is to be closed, as the weights or springs hold it up, as shown in Fig. 4, it will be seen that the upper edge of the guard will strike the stop 14 before the shell has arrived at its highest position. The

further movement of the shell causes the inclined surface to move against the valve, and the levers by which the valve is suspended pivoting on their fulcrum-points will raise the weight or extend the springs, as the case may be, so as to allow the shell to' continue its movement after the valve has come in contact with the stop, and by this movement the inclined face gradually acts to force the valve closely against its seat.

For the purpose of operating the shell and the valve I have shown a loose nut 15, which is here shown as located in a transverse opening made near the end of the shell. A screw 16 passes through the cap 17 of the casing, and its threaded end enters the nut. The screw-shank has asuitable collar turnable in the cap without advancing, so that the rotation of the screw will act to move the shell and valve.

In order to relieve the moving parts of the frictional pressure, which would otherwise be caused by the force of the water acting to press the shell against the opposite side of the casing to that in which the water-inlet is located, I employ one or more rollers 18. In the present drawings I have shown but one of these rollers; but it will be manifest that a plurality may be employed, if desired. The face of the roller travels against the side of the casing, which is parallel with the guides 6, and in order to insure a rolling movement I have shown racks 19 fixed upon each side of the shell, and similar racks 20, fixed in the face, against which the roller travels and be yond the ends of the smooth portion of the roller. These ends are reduced and carry upon them pinions 21, which pinions travel in the racks before described, and thus pre vent the roller from changing its position, maintaining the roller transverse to the line of movement of the shell.

When the shellhas been moved within the casing to such a point as to close the valve, the roller or rollers will lie in such position with relation to the valve as to direct a central pressure so as to close the valve evenly against its seat. When the shell is moved in the direction to open the valve, the roller 18, by reason of its movement between the inner face of the casing and the contiguous face of the shell, will travel between the two, and when the shell is moved to open the valve at the limit of its opening the roller will come in contact with lugs 28, carried by and projecting from the smaller end of the shell and thus limit the movement of the roller and prevent its getting out of position.

While this gate may be used in any position, it is particularly designed to be used in an inverted position or with the larger end downward when employed where the opening of the valve must be effected from below. It is also adapted to be used in a horizontal or inclined position by the use of springs to counterbalance the valve and insure its proper movements with relation to the shell and water-opening.

The guides 6 prevent the shell from tilting and also maintain the shell in its proper line of travel if pressure is brought upon it from the roller side of the gate. The pinions 21 are loosely journaled on the ends of the roller 18, and the valve or disk 8 is loosely connected with the shell by the lever 11, and its movement is limited by the play allowed to the levers. The stop on the shell serves to hold the roller in place while assembling, but may be omitted if the racks are extended with reference to-the shell and casing.

It will be understood that, while I have described a screw by which the shell is reciprocated, any suitable or well-known power mechanism may be substituted therefor without changing the operation of the device.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
